Search missing shared folders inconsistently

There are a few things that may result in missing results from the search functionality on the Dropbox API like this.

First, note that if you are searching for new changes, they may not be returned due to a delay from indexing. If you wait and try again later, it may be returned.

Also, the interface is paginated, so if the search has multiple results to return, you may not get everything back on one page. You need to always check the 'has_more' value returned by /2/files/search_v2 (or 'more' value if using the deprecated /2/files/search) and if it's true, call back to /2/files/search/continue_v2 to get more results.

Additionally, if the search has a large number of results, it's possible they can't all be returned. In that case, you should try a more specific query, or use /2/files/list_folder[/continue] instead. 

If none of that seems to be the issue though and you'd like us to look into this specifically for you, please feel free to open an API ticket with the details.
